DOOR-CHECK.

Specification of Letters Patent.

Application filed April 5, 1909.

Patented Jan. 10, 1911.

Serial No. 488,074.

To all whom it may concern:

Be it known that we, JAMES REES and JAMES l/VILLIAM HENRY BEES, bothsubjects of the King of Great Britain, both residing at 7 Delvertonroad, l/Valworth, in the county of London, England, engineers, havejointly invented certain new and useful lmprovements in and Relating toDoor-Checks, of which the following is a specification.

This invention relates to door closers and checks of the kind that areadapted for use with doors hung so as to be capable of swinging to bothSides of a normal closed position, and in which a spring, inclosed in acasing and wound as the door is being opened, tends by its reaction, onthe door being released by the opener, to impart a closing movement tothe door, which movement is controlled by a checking device alsocontained in the casing and actuated by the spring.

The invention consists in novel features and arrangements as hereinafterreferred to and described.

The invention is illustrated in the accompanying drawings inwhich-Figures l and 2 are respectively an elevation and plan of a doorcheck and closer embodying this invention and applied to a swing doorshown in the closed position; Figs. 3 and 4 are plans of the sameshowing the door swung into two positions on either side of the closed'positiong and Fig. 5 is a section of a portion of the easing showing inpart a closing Ispring and checking device.

Referring first of all to Figs. l, 2 and 5 a casing a comprising a bodyand a cap 0, contains checking and closing devices which may be of anysuitable kind comprising a closing spring 1" having its outer end suit-Iably attached to the casing, an actuating spindle connected by means ofa crank arm Z2 to a checking position s. The casing is closed by the topplate or cap c having two arms c and c2 and fixed in some suitable waythereto. This cap has a hole through which passes a depending boss d ofa toothed sheath or ratchet d bored so as to fit loosely around theactuating spindle l). f is a pintle plate suitably secured to a lintelor lining g over the doorway. The casing a is supported from this pintleplatef by a bracket or arm e pivoted thereon at f and pivotallyconnected at c3 to the cap arm c. At the cap end of this bracket thereis preferably a lateral stop Q adapted to engage,

for certain positions of the bracket, with the pintle plate; at theother end on the underside of the bracket there is an abutment p adaptedto cooperate with a stop cL formed on or attached to the cap c. Carriedby the pintle plate below the pivot f there is a segmental projectingguide or clutch f2 which cooperates with a projection c5 formed on theupper surface of the cap for a purpose hereinafter referred to. Anoutside crank j is secured in position on the end of the spindle o,above the ratchet, by a nutc or other suitable means. The pintle plateis connected to this crank by a link z' which is pivotally attachedthereto at z" and to the pintle plate at the pivot 2. This link can beadjustably correlated with the ratchet wheel in some suitable way, suchas by the engagement of one of its teeth with a screw or pin Z. To thedepending boss d of the ratchet the inner end of the closing spring r issuitably fixed. On withdrawing the pin Z from the ratchet the latter canbe turned and the spring wound so as to impart to it whatever initialtension may be necessary and it may be retained in the adjusted positionby the re-insertion of the pin. The casing is connected to the door by aclosing member., comprising an adjust-able link and rod m n, connectedat c to the cap c2 and at a to the bracket a2 suitably fixed to the door7L.

In Figs. 3 and l the door is shown as open in two different positions,one en either Side of the normally closed position indicated in Fig. 2.In Fig. 8 as the door is swung open about the pivot o or on suitablehinges the bracket arm c er .its stop Q remains in abutment with thepintle plate f whereby the casing moves around the pivot c3, whichmovement causes the crank j to be rotated whereby the tension of thespring is further increased and the checking piston moved outwardly,that is to the left in Fig. 5, to an operative position, in a mannerusual in such devices. On the door being released by the opener thespring begins to unwind and tends both to return the casing and the doorby means of rod n, to the normal closed position and to impart an inwardmovement to the piston to control the closing movement of the door inthe well known way. .l ust as the door closes the rounded projection 3on the link c' engages one side of the stop c4 on the cap c and guidesthe casing into the normally closed position. When the door` is swunginto the position shown in Fig. I the abutment y) remains in engagementwith the stop 0^* whereby the bracket c turns about the pivot carryingthe casing with it and the relative movement of the casing and theactuating spindle causes the spring to be wound and the pistons moved toan operative position; then as soon as the door is released by theopener the spring r tends to pull it back to the closed position bymeans of the rod a. During the opening movement the projection 0" on thecap remains in engagement with the clutch f2 and during the backwardmovement the projection engages the clutch f2 whereby the casing isprevented from turning around the pivot c3, which it might otherwise do,but, with the bracket e, it is constrained to continue to swing aboutthe pivot f and thereby cause the checking device of the apparatus tooperate before the door again arrives at the normal closed position andthe stop Q again engages the plate f.

Having thus described the nature of our invention and the best means weknow of carrying the same into practical effect, we claim l. A closerand check for swing doors of the character referred to, comprising acasing and closing and checking devices operatively mounted. therein,and means including a two armed cap whereby the casing may be ipivotally supported from the door lintel and operatively connected tothe door; substantially as described.
